Warm Tips

Q1: Why I can't open the Lid? Filling a water cup with hot water triggers thermal expansion in both the cup and its lid. The steam produced by the evaporation of the hot water boosts the air pressure inside the container, resulting in a pressure differential with the outside environment. Consequently, the lid becomes challenging to open, even for an adult.

A1: ADVISE: When filling a container with hot water, you need to get rid of letting the hot water touch the lid. This can greatly facilitate the process of opening the lid later on.

Q2: Why does my tumbler leak water?

A2: You must flip the straw and return it after filling the water.
